I tried to BF all of mine but most of them ended up being FFd. All of my kids needed some suplimentation at the hospital.

One tip I picked up - SAVE your "throw" away bottles and the nipple rings! (The nipples themselves don't hold up to being boiled but the rings you can keep and you WILL need them ) The bottles are glass so they can be boiled at home later and they are the perfect little size until baby moves up to bigger bottles.
